EN 16482: 2014 | IN GJL-500-7C

GGG-50/7

Available formats: Sheet metal, plates, bars, profiles and wires.

features

GGG-50 increases its perlitic structure compared to 400-15, achieving greater wear resistance and greater strength in response to heat treatment, while maintaining good machinability and excellent surface finish. Absorbs noise and vibration damping well. Complies with EN 16482: 2014 | IN GJS500-7C.

Brinell hardness

170-225 HB with 10 mm diameter ball and 3000Kg load. depending on the size of the section. Hardness readings are taken throughout the entire section of the bar. The hardness values for rectangles depend on the relationship between height and width and can be supplied upon request.

Micro structure

It contains nodular (spheroidal) graphite type V & VI according to ISO 945. The periphery contains approximately 200/250 nodules / mm2 and is predominantly ferritic, with a nucleus containing 90/150 nodules / mm2. The core matrix is ferritic / perlitic mixture (10-50% perlite). Cold carbides will be less than 5 %, well dispersed.
